Question

The distance between NY and Boston is 306 km. How long is it on a map (in cm) drawn at a scale of 1:1,200,000?

Answer 1

Answer: 25.5 cm.

Explanation:

Given distance between NY and Boston = 306 kilometers.

We are given scale factor of map in cm = 1:1,200,000.

1 km in cm = 100000cm.

Therefore,

306 km in cm = 30600000

Therefore, each 1 kilometer is equal to 1/1200000th km on the map.

Therefore,

306 kilometers =
`30600000 * (1)/(1200000)`

= 25.5 cm.

Therefore, it is 25.5 cm on a map drawn at a scale of 1:1,200,000.
